Configuration through the web interface

Modem Emulation profile

The Modem Emulation profile allows a Digi device to sends and receive modem responses to the

serial device over the Ethernet instead of PSTN (Public Switched Telephone Network). This

profile allows maintaining the current software application but using it over a less-expensive

Ethernet network. The commands that can be issued in a modem-emulation configuration are

described in the Digi Connect Family Command Reference.

Industrial Automation profile

This port profile is available in Digi devices that support Industrial Automation (IA) and the

Modbus protocol. It has serial port settings appropriate for the Digi Connect WAN IA’s use in IA

applications. It allows you to control and monitor various IA devices and PLCs. Serial ports for

Digi Connect WAN IA devices are set to use this port profile by default. The default settings for

the Digi Connect WAN IA and in this port profile should be sufficient for most IA applications. If

you need to change the settings from the defaults, use the “set ia” command, documented in the

Digi Connect Family Command Reference.

Dialserv Profile

The DialServ Profile allows connecting a Digi DialServ™ device to the serial port. Digi DialServ

is an RJ-11 phone line simulator that allows legacy devices with built-in modems to communicate

across LANs/WANs. This profile configures the Digi device to connect/tunnel serial data to an

external host when the DialServ receives an incoming call, causes the DialServ to make outgoing

calls, and tunnels TCP data from the incoming connection over the Dialserv when TCP traffic is

received on the configured ports on the Digi device.

Important: Use of this profile is required for DialServ interoperation.

Custom Profile

The Custom port profile displays all serial-port settings, which can be changed as needed. Use the

Custom profile only if the use of the serial port does not fit into any of the predefined port profiles,

for example, if network connections involve a mix of TCP and UDP sockets.
